Boom Racing has introduced an active toe in & out rear hub system for the Sakura D4 RWD or AWD. This is a must have performance upgrade for all those D4 drifters out there looking for some upgrades for their cars it allows the rear wheels to toe in & out as the suspension travels up and down. The way it works is when you hit the throttle the suspension is compressed under acceleration and the rear wheels will toe in giving you more acceleration. Under deceleration and breaking the rear will lift up and the suspension will extend therefore giving the system toe out which in return giving it more breaking friction. Under normal ride height / load it can be set to 0 degree toe or whatever degree toe in or out you desire for a nice friction free roll at the rear end when vehicle is moving.
